一个特殊的 Json 『美化』工具

之所以叫美化而不叫格式化，是因为是给人看的，改变了数据结构　

各个业务之间传递数据，喜欢用 jsonstring

传递层级一多，满屏的转义符，没法看了

看了一些格式化工具，都是保持原来数据结构，以保证程序正确运行为先，没有这种自动美化的

美化后数据不能直接喂给程序哦~~

原始的
{
    "l": 2,
    "v": "{\"l\":1,\"v\":\"{\\\"l\\\":0,\\\"v\\\":\\\"{\\\\\\\"a\\\\\\\":[{\\\\\\\"l\\\\\\\":2,\\\\\\\"v\\\\\\\":\\\\\\\"{\\\\\\\\\\\\\\\"l\\\\\\\\\\\\\\\":1,\\\\\\\\\\\\\\\"v\\\\\\\\\\\\\\\":\\\\\\\\\\\\\\\"{\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"l\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\":0,\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"v\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\":\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"{\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"value\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\":\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"AAAA\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"}\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"}\\\\\\\\\\\\\\\"}\\\\\\\"},{\\\\\\\"l\\\\\\\":1,\\\\\\\"v\\\\\\\":\\\\\\\"{\\\\\\\\\\\\\\\"l\\\\\\\\\\\\\\\":0,\\\\\\\\\\\\\\\"v\\\\\\\\\\\\\\\":\\\\\\\\\\\\\\\"{\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"value\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\":\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"BBBB\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"}\\\\\\\\\\\\\\\"}\\\\\\\"}],\\\\\\\"value\\\\\\\":\\\\\\\"CCC\\\\\\\"}\\\"}\"}"
